colemak mod-dh

is a Colemak mod that attempts to tweak the Colemak layout by reducing the lateral movement of the index fingers, notably for the D and H keys, so they are pressed by the index fingers on the bottom row instead.

This allows moving the difficult to reach B key to the top row, restoring the G key to its Qwerty position with the following Poker 2 programming..

For the ANSI layout Poker 2 keyboard, the bottom left hand row is further shifted (relocating the Z key) to introduce hand position symmetry, allowing the left hand to curl its fingers rather than twist the wrist, similar to the right hand finger motions, reducing wrist strain. This is a Colemak win-win: optimal finger travel and added comfort.

adding just an additional swap of the Qwerty H and M keys to maintain the WASD-like Qwerty navigation cluster!

The f “find” command is restored and combined with the t “till” command, with “till” arbitrarily remapped to Ctrl and Alt key sequences.

The programmability of the Poker 2 keyboard makes changes to the standard Colemak layout possible, being portable enough to be carried and connected to any computer.

Now to retrain some muscle memory..
